Hello, I have a bad breath issue and I believe it s coming from my throat/nose. I have captured a video of a back of my throat and viewing it afterwards, I ve noticed yellow areas, which might be a result of chronic post nasal drip I ve got. If you want to take a look, I have uploaded it on youtube: https://www.youtube.com/watch?v=ZLwyeCn3Fcw . If you see any abnormalities, could you please reply and give me some advice on how to get rid of my bad breath? Thank you
